Introduction This draft identifies criteria to be used in evaluating and selecting Control and Reporting Protocols described by [I-D.ietf-lmap-framework]. Both mandatory and comparative criteria are identified for these protocols. 1.1. Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 2. Control Protocol Criteria 2.1. Mandatory Criteria Following is a list of criteria that a Control Protocol is required to support. Protocols that do not support these criteria will not be considered appropriate for selection as a Control Protocol. Note that although the protocol may support the criterion, it is not necessarily the case that the criterion is mandatory to implement according to the protocol specification. CP-MUST-1 There must be a mechanism that allows a Controller to cause a session to be established with a MA. CP-MUST-2 There must be a mechanism that allows a MA to cause a session to be established with a Controller. Stark & Carey Expires July 19, 2015 [Page 2] Internet-Draft LMAP Protocol Selection Criteria January 2015 CP-MUST-3 The protocol session must be capable of being secured using certificates, as described in [I-D.ietf-lmap-framework]. 2.2. Comparative Criteria Following is a list of criteria that can be used to differentiate among Control Protocol candidates. For each criterion, it is also indicated what is considered "better" for a candidate protocol to support. CP-DIFF-1 How many exchanges are required to send a complete instruction set? (less is better) CP-DIFF-2 How many exchanges are required to send a status update? (less is better) CP-DIFF-3 Is it possible to provide partial updates? (yes is better) CP-DIFF-4 Are there any special mechanisms (other than STUN/TURN/ ICE or using port forwarding pinholes, PCP, UPnP IGD, etc.) for NAT/firewall traversal? (asked out of curiosity, but not expecting anything) CP-DIFF-5 How many bytes of overhead are required to send a complete instruction set? (less is better) CP-DIFF-6 How many bytes of overhead are required to send a status update? (less is better) CP-DIFF-7 How widely used is the protocol and/or its protocol elements in mass market devices? (widely is better) CP-DIFF-8 What mechanisms exist to ensure interoperability of MA and Controller implementations? (existence of something is better) CP-DIFF-9 Are the components of the protocol available as open source? (yes is better) CP-DIFF-10 What ecosystem of tools exists for developers implementing the protocol (include tools for data model creation)? (existence of useful tools is better) CP-DIFF-11 Is the protocol versionable? (yes is better, or is this mandatory?) Stark & Carey Expires July 19, 2015 [Page 3] Internet-Draft LMAP Protocol Selection Criteria January 2015 CP-DIFF-12 If yes, what is the process for extending the protocol? (for information) CP-DIFF-13 What are the encodings supported by the protocol (SOAP, JSON, XML, etc.)? (for information) 3. Report Protocol Criteria 3.1. Mandatory Criteria Following is a list of criteria that a Report Protocol is required to support. Protocols that do not support these criteria will not be considered appropriate for selection as a Report Protocol. Note that although the protocol may support the criterion, it is not necessarily the case that the criterion is mandatory to implement according to the protocol specification. RP-MUST-1 There must be a mechanism that allows a MA to cause a session to be established with a Collector. RP-MUST-2 The protocol session must be capable of being secured using certificates, as described in [I-D.ietf-lmap-framework]. 3.2. Comparative Criteria Following is a list of criteria that can be used to differentiate among Report Protocol candidates. For each criterion, it is also indicated what is considered "better" for a candidate protocol to support. RP-DIFF-1 How many exchanges are required to send a report? (less is better) RP-DIFF-2 Does it allow for sending multiple reports in a session? (yes is better) RP-DIFF-3 Is there a capability for long-lived sessions. (yes is better) RP-DIFF-4 Is compression supported? (yes is better, or is this mandatory?) RP-DIFF-5 How many bytes of overhead are required to send a report? (less is better) RP-DIFF-6 How widely used is the protocol and/or its protocol elements in mass market devices? (widely is better) Stark & Carey Expires July 19, 2015 [Page 4] Internet-Draft LMAP Protocol Selection Criteria January 2015 RP-DIFF-7 What mechanisms exist to ensure interoperability of MA and Collector implementations? (existence of something is better) RP-DIFF-8 Are the components of the protocol available as open source? (yes is better) RP-DIFF-9 What ecosystem of tools exists for developers implementing the protocol (include tools for data model creation)? (existence of useful tools is better) RP-DIFF-10 Is the protocol versionable? (yes is better, or is this mandatory?) RP-DIFF-11 If yes, what is the process for extending the protocol? (for information) RP-DIFF-12 What are the encodings supported by the protocol (SOAP, JSON, XML, etc.)? (for information) 4. Acknowledgements Members of LMAP WG. 5. IANA Considerations This memo includes no request to IANA. 6. Security Considerations Candidate Control and Report protocols are required to meet security requirements identified in [I-D.ietf-lmap-framework]. 7.
